摘要

PURPOSE: A manufacturing method of a yellowish Schizandra dye is provided to manufacture a Schizandra dye which is environmentally-friendly and has excellent sterilizing effect, by extracting a pigment component from Schizandra. CONSTITUTION: A manufacturing method of a yellowish Schizandra comprises a step of preparing a raw material by extracting, washing, and pulverizing a Schizandra; a step of putting the Schizandra into an ethanol, heating the same in water at 70-95°C for 5-7 hours to obtain a Schizandra extract; a step of removing Schizandra residues from the Schizandra extract; and a step separating the ethanol from the Schizandra extract by a rotary vacuum evaporator. The Schizandra is a mixture of one or more selected from a Schizandra skin, a Schizandra fruit, and a Schizandra seed.
